Abstract
The utility model provides a magnetic adsorption type ground wire grounding device which has the advantages of low cost and long service life. In the device, the lower part of a wire clamp is provided with a copper bottom plate; one end of the copper bottom plate extends to the upper part of the wire clamp and is fixed on the wire clamp through a copper wire clamp, a bolt and a nut; and a magnetic body is arranged on a part corresponding to the copper bottom plate in the wire clamp. When the device works, a wire is integrally connected with the copper bottom plate through the bolt, the nut and the copper wire clamp to become a conductor; the copper bottom plate is adsorbed at any position, where a workpiece is required to be welded, by the magnetic body on the copper bottom plate, so that a cable on the workpiece side of an electric welding machine is closely connected with a base material of the workpiece to be welded, and furthermore, a current loop during welding is formed. The device is in surface contact with the workpiece, so that less heat is produced during heavy-current continuous welding, and burning scars caused to the workpiece due to transient heavy current are effectively avoided; the device can be adsorbed to the workpiece through all-position adsorption; compared with the conventional ground wire clamp, the device is convenient and flexible and is suitable for various sections and plates; and the device is suitable for various welding machines.
Description
Technical field
The utility model belongs to the electric welding technical field, relates to the aid grounding wire device that a kind of electric welding is used, and relates in particular to the ground wire grounded device of a kind of magnetic force adsorption type.
Background technology
Ground wire grounded device is an indispensable aid in the electric welding process, and its effect is that electric welding machine workpiece side cable is connected with workpiece mother metal to be welded, the current circuit when forming welding.Traditional ground wire grounded device is a ground clamp, and it is made up of wire clamp body, spring, copper sleeve, bolt and nut, and lead connects by bolt and nut, become one with copper sleeve, copper sleeve is clamped on the iron workpiece that needs to connect, and it is linked into an integrated entity, and plays the conductor effect.Owing to passing through of big electric current on the ground clamp in the electric welding process, the time very easily generate heat in a contact, cause spring after using under the long-time high temperature, to be easy to fatigue, lose elastic force and cause inefficacy, make ground clamp holding workpiece fully, cause loose contact, make electric current instability in the electric welding process, thereby influence the quality and the operating efficiency of weld seam, and cause the burn of surface of the work.Therefore, traditional ground clamp needs to change at any time.According to statistics, the annual ground clamp that probably needs 25 ~ 30 of replacings of electric welding machine so not only causes very big waste, and has increased the electric welding cost.
The utility model content
The purpose of this utility model is in order to overcome problems of the prior art, provides that a kind of cost is low, the ground wire grounded device of the magnetic force adsorption type of long service life.
The ground wire grounded device of magnetic force adsorption type of the present utility model comprises the wire clamp body, and the bottom of described wire clamp body is provided with copper soleplate, and an end of this copper soleplate extends to the top of wire clamp body, and is fixed on the wire clamp body by copper cash folder, bolt and nut; Corresponding copper soleplate place is provided with magnetic in the described wire clamp body.
Be handled easily and mobile, the top of online clamp is provided with handle.
During work, lead links into an integrated entity by copper cash folder, bolt and nut and copper soleplate, becomes conductor; Magnetic on the copper soleplate is adsorbed on any position that needs welding work pieces with copper soleplate, and electric welding machine workpiece side cable and workpiece mother metal to be welded are closely coupled together, thereby forms the current circuit when welding.
The utility model has the following advantages with respect to prior art:
1, be that face contacts with workpiece, conduct electricity very well and copper soleplate has good thermal diffusivity, continue the heat less (temperature rise is generally about 30 ℃) that produced in the process of welding at big electric current, effectively avoided workpiece being produced the cable cover oxidization burning loss that cause because of localized hyperthermia at burn scar and cable connector position because of instantaneous large-current.
2, workpiece is adsorbed in the position entirely, and more traditional ground clamp is convenient, flexible, applied widely, is applicable to various section bars, sheet material (except the non-ferrous metal); Be applicable to that various welding machines use.
3, simple in structure, cost of manufacture is low, and is reliability and durability, long service life.Wire clamp is saved about 1000 yuan of cable ground connection aid expense electric welding machine year for every more traditionally.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the ground wire grounded device of a kind of magnetic force adsorption type comprises rectangle wire clamp body 1.The bottom of online clamp 1 is provided with copper soleplate 2, and an end of this copper soleplate extends to the top of wire clamp body, and is fixed on the wire clamp body 1 by copper cash folder 5, bolt and nut 4; The position of corresponding copper soleplate 2 is provided with magnetic 3 in the online clamp 1.
For ease of operation, the top of online clamp 1 is provided with handle 6.
During operation, this device is positioned on the workpiece mother metal to be welded, the lower copper base plate 2 of wire clamp body 1 is contacted with the welding work pieces mother metal, and under the effect of magnetic, copper soleplate 2 closely is connected with the welding work pieces mother metal.Lead links into an integrated entity with copper soleplate 2 by copper cash folder 5, bolt and nut 4, becomes conductor; Electric welding machine workpiece side cable and workpiece mother metal to be welded are closely coupled together, the current circuit when forming welding.
